CRAY RESEARCH AND CSAR ANNOUNCE LEADING
AUTOMOTIVE RESONANT CAPABILITY FOR IMPROVED NVH
DESIGN OPTIMIZATION

EAGAN, Minn., AGOURA HILLS, Calif., Feb. 27, 1995 --  Cray
Research, Inc. and CSAR Corporation today announced that
Version 94 of CSA/NASTRAN has been benchmarked on a Cray
Research supercomputer and has successfully simulated the
resonant frequencies of an entire car model with more than 1.5
million degrees of freedom.  The two companies said that this
size of problem is nearly 30 times what could be accomplished
only five years ago and that the Cray/CSAR combination
provided superior time-to-solution and accurate results. 
 
CSA/NASTRAN is a computer program developed, maintained,
and marketed by CSAR Corporation to industrial and
governmental sites around the world.  It is used by engineers to
determine the stress, vibration, and acoustical properties of
structures through computer simulation before prototyping
even begins, helping save manufacturing companies and other
organizations time and money in bringing new products to
market. 

According to the companies' officials, the Cray/CSAR
technology is important to the auto industry's efforts in the
area of improved Noise Vibration and Harshness (NVH) for new
cars.  This automotive benchmark proves that auto engineers
can move to the next stage of applying simulation to NVH
design.  

"The ability to successfully solve a problem of this size and
complexity should prove to auto engineers that they can now
simulate a full car body's natural frequencies and also take
into account wheel, engine and road terrain frequencies and
apply design optimization methods for improved passenger
comfort," according to Derek Robb, vice president of Cray's
Applications Division.  "This benchmark also shows how well
CSAR has adapted CSA/NASTRAN to run on Cray systems.  We
are extremely pleased to be able to announce results like this
and to point out that no other computer on the market today has
the capability to handle this type of problem."  

Cray and CSAR completed the test in under 10 (9 hours, 51
minutes), the two companies said.  In subsequent verification
testing, the auto customer providing the benchmark finished
the test in under nine hours on a single-processor and
considerably faster using four processors of the CRAY C90
system in parallel.  

"This level of performance bolsters our claim to run the
largest, most difficult problems rapidly and efficiently," said
Dr. R. Swami Narayanaswami, President and CEO of CSAR.  "We
owe a good deal of this success to Cray and the excellent
technical assistance they have provided us over the years.  In
this case, our automotive customer reports that this time-to-
solution for this large problem is particularly useful in
advancing NVH design optimization.  The partnership between
Cray and CSAR continues to provide extraordinary returns for
our mutual customers."

CSAR Corporation is a privately held company headquartered in
Agoura Hills, CA.  Its products, CSA/NASTRAN, CSAR/OPTIM2,
and CSAR/SIZING2 are used by major industrial companies
throughout the world, including the U.S., Japan, U.K., Germany,
Sweden, India, and the People's Republic of China.

Cray Research Inc. (NYSE:CYR) is headquartered in Eagan, Minn. 
Cray Research offers a broad-range of supercomputing systems
that begin as low as $225,000 (U.S. list price).  The company's
systems are used by industrial customers worldwide in the
automotive and automotive supplier, aerospace, electronics,
energy, petroleum, chemical, pharmaceutical, and
telecommunications industries.
